Hello there, I'm using RaspberryPi and python graphical application to control some stuff. Critical for me is fast boot time. I'm using Raspbian Lite with some adjustments like disabling most of services etc, to aquire boot time less than 4 seconds. However, my python app uses Tkinter, so it's need ...

Maybe 2n2222 transistor? It handles up to 65V/600mA if I remember correctly(anyway, for sure it will handle ur diode) and still can be activated by Raspi, so would be suitable for this, any maybe many more applications in the future.
Moreover very cheap and extremlly popular around the world.

Hello there, I'm quite new in Raspi and currently I'm heading to make headless, fast booting board with python app to controll some GPIO trough WiFi. I'm using Rasbian Lite and I've already did some improvements to boot time and it currently takes from 10 do 15 seconds. However, the longest starting...
